Well I've just installed a JP FX12 T03 and a 21t pinion, and after 3 tanks of running in I feel it will require the 22t pinion to prevent wheelspin.
Just how much torque does a JP have?
(the STS Dragon could not pull a 21t pinion)
Just back from the track with my FX-05. Ill be fitting the 21/27 pinions as its ridiculously fast! 21 is ok with foams!
